IMPROVEMENT IN MEDICAL INHALERS.

Specification forming part of Letters Patent No. 145,679, dated December 16, 1873; application filed November 3, 1873.

To all whom it may concern Be it known that I, JAMES CASPAR PARKIN- SON, M. D., of Vineland, Cumberland county, State of New Jersey, have invented an instrument for the purpose of enabling persons the more perfectly and conveniently to inhale the atoms or vapor of any medicinal substance into the nose, throat, bronchia, or air-cells of the lungs, for catarrh, ozena, diphtheria, tonsilitis, tracheitis, and other affections of the mucous membranes of the air-passages, in-

eluding affections of the lungs, of which the following is a specification:

The body A of this instrument is globular in form, having two prolongations, B O, opposite to each other. The body or globular portion A constitutes a chamber for the reception of prepared sponge, or other porous and retentive material, designed to receive the medicine, the vapor or atoms of which are to be inhaled. The superior elongation or neck B is designed to be applied to the nostril, or introduced into the mouth, according as the disease to be removed is in the nasal passages, or in the throat or lungs; also, to receive the extremity of a tube to be hereinafter mentioned. Through the inferior prolongation O the air is supplied that, in breathing, passes through the sponge and conveys the medicine to the affeeted parts. I have also adapted a tube, D, fitted at one extremity with an elastic ring or pad, E, so as to accurately and closely fit into the mouth of the superior elongation or neck and ulcers in diphtheria, and into the larynxand trachea in eroup.

The instrument may be made of any dimensions, but, as it is designed especially to carry about the person, three to four inches is the size best adapted. It can also be made of any material, though glass is the most suitable for the purpose. A metal cap may also be fitted to each oritice to close them, when not in use, to prevent the escape of the vapor; but I prefer cork.

I am aware that a single bulb is not new, and that inhalers are made of a single piece of glass; but the advantage mine possesses over these is that the tube D may be made of any required length by sliding it within the bulb.

- I claim- The inhaler, composed of the glass bulb A with its two openings, 0 and B, and the tube D secured in the openings B by the elastic ring E, or its equivalent device.
